Automatic transmission having a pressure regulator with flow force compensation

An automatic transmission having a pressure regulator with flow force compensation. The pressure regulator includes a valve body having a valve bore and at least one inlet and at least one outlet adapted to provide fluid communication with a source of pressurized hydraulic fluid and a return to the source of pressure. A valve member is slidingly disposed within the valve body that includes at least one valve element having an outer diameter and a metering face. The metering face is adapted to control the flow of pressurized hydraulic fluid between the inlet and the outlet of the valve body. The metering face includes a flow force compensating annular void disposed adjacent to the outer diameter that is defined by a lead angle α measured between the outer surface and a line intersecting the outer surface and tangential to the annular void.

Hybrid vehicle combined type energy management method

The invention relates to a hybrid vehicle combined type energy management method. The hybrid vehicle combined type energy management method comprises the following steps that high-voltage bus demand power, a torque requirement of a drive motor and a torque requirement of a brake system are obtained through signals such as an accelerator pedal, a brake pedal opening degree and an actual rotation speed of the drive motor and checked maximum charge-discharge power of an energy storage system; a SOC of the energy storage system is corrected based on the checked maximum charge-discharge power of the energy storage system and the bus power; a basic switching strategy based on the upper and lower limitation of the SOC and an engine switching control strategy with trigger-turning-on during high-power requirements and trigger-turning-off during large brake are developed, an improved equivalent fuel consumption minimization strategy is used and important parameters are optimized by self-learningmethod to realize the optimal power distribution; and finally, the engine switching strategy and an energy management strategy are combined. Compared with the prior art, the hybrid vehicle combined type energy management method enables the control of the engine and the drive motor to be more accurate and efficient, and the oil saving potential under the single energy storage system is improved, and the cycle life of a lithium battery pack under the single energy storage system is prolonged.

Motor operated valve apparatus and motor operated valve controller

A motor operated valve apparatus includes: a motor driven valve; a drive unit configured to drive the motor; a control unit configured to control the drive unit; and a communication unit configured to communicate with an external controller. The control unit starts control of the motor operated valve according to a command from the external controller; drives the motor in a valve closing direction at start of the control, detects a load on the motor based on a drive pulse output by the drive unit for driving the motor, and sets a driven state when the detected load reaches a predetermined reference value to be a valve switching point of a valve section; and drives the motor relative to the valve switching point of the valve section to perform control so that an opening degree of the valve section becomes a value corresponding to a control command value.
